Towards building jlibusb with gradle

* rename package ch.ntb.inf.libusbJava to ch.ntb.usb/Device.java
* separate main, app, test and demo source files
* reorganise static library files
* add prebuilt libraries for testing purposes
* move auxiliary files to appropriate directories
* remove obsolete files
